GRATE.

SPECIFICATION forming part of Letters Patent N o. 418,849, dated January7, 1890. Application filed November 2, 1889.' Serial No. 329,046. (Nonlodel.)

To all whom t may concern.-

Be it known that I, WILLIAM C. METZNER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Stove-Grates; andIdohere- I by declare thevfollowing to be a full, clear, and

exact description ofthe invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawing, and v to letters of reference markedthereon, which Y form a part of this specification.

This invention relates more particularly to vgrates for the fire-pots of.cook-stoves and the invention has for its object to provide a gratewhich shall be adapted to be fitted into repots of dierent sizes, andwhich shall at the same time be of simple and cheap construction.

The drawing is a perspective view of a grate elnbodying my improvement.

The grate extends horizontally from its rear portion forward a distanceequal to the usual width of the fire-pot, and 'then rises a shortdistance at th'e front. The entire horizontal portion is designated bythe letter A, and the upright portion by the letter B. The grate isconstituted, mainly, of the horizontal and substantially-parallelribsO.l These are united at the front by a web D, which latterconstitutes the upper portionof the part B of the grate. united by a webE, extending transversely across the grate at a short distance from therear edge of the grate, so that the rear ends of said ribs are leftfree. The portions of said nribs between their ends and the web E arepreferably provided with breaking-grooveso. The web Emay be of the fulldepth of the ribs C, and may consequently be narrow, so as to offerlittle obstruction to the rising of the air and the falling of theashes. The entire portion of the grate at the rear of said web E is thenopen in the Vsame manner as the portion of the grate between the webs Eand D are open. AConsequently that portion of the grate is,in`fact, agrate and allows the passage of ai-r and ashes as freely as does theportion of the grate in front of the web E.'

The opposite ends of said ribs are It is to be noted that a grate for acook- -stove must be open as far to the rear as possible, in order toavoid the accumulation of ashes upon the rear of the grate and againstthe wall of the baking-oven. If said part of the grate is closed, ashesaccumulate there and keep the heat of the fire from the wall of theoven. By leaving the same open the portion of the tire-pot adjacent tothe oven-wall may be kept clear of ashes, and airA lnay be constantlydelivered to the portion of the fire-pot adjacent to the oven, so thatan effective fire may be maintained adjacent to *the oven-wall.

It is well known that in the use of an ordinary cook-stove theintelligent cook or housekeeper carefully removes all ashes and deadfuel from the rear portion of the fire-pot, so as to establish a strongfire contiguous to the oven-wall. The more open a grate is at its rearportion the better this rear'iire may be made. By moving the web Eforward from the rear portion of the grate I am enabled to fit the grateinto ire-pots of different sizes. If the entire grate is too wide, theends of the ribs C may be broken across the entire length of the grate.If the 'fire-pot is irregular in width from warping or other cause, thenonly a portion of the ribs may be broken off, or

ferent lengths to cause the grate to iit an irregular back aids inarranging the grate with the largest possible amount of opening along47the rear or oven wall of the fire-pot.

The grate may or may not have a movable section F, located forward ofthe web E.

I claim as my inventionl. In a stove-grate, ribs C, supported at theirfront b ya web D and forward of their rear ends by a web E, whereby therear ends of said ribs are left free and the rear portion of the grateis left open and the ends of said ribs are adapted to be broken off,substantially as shown, and for the purposes set forth. 2. In astove-grate, ribs C, supported at their frontby a web D and forward oftheir rear IOO ends by a web E, and the portions of said ribs Intestimony whereof I affix my signature,

said ribs are left free and the real' portion of 1WKLLAM C. METZNER.
